USP9Y and Infertility: It appears intriguing that several coding (AMELY, PCDH11, SRY, TGIF2LY, TSPY3, and USP9Y) and non-coding (TTTY2, TTTY4C, TTTY5, TTTYY6, TTTY8, TTTY10, TTTY14, TTTY21, TTTY22, and TTTY23) genes commonly displayed low expression in samples from fertile patients and high expression in samples from infertile patients with very little influence of OE on their expression profile.
